Plugin Compatibility Checker for CakePHP
summary
An open JSON archive called PDFF captures CakePHP’s OOP API per major version (Cake archives range ~3–20 MB) and drives a static analysis pipeline that audits plugins for missing symbols, argument/name mismatches and deprecated uses. Running PDFs removes framework stubs and drops false positives (426 reported before) to zero undefined framework symbols for tested plugins; DebugKit shows compatibility with the in-progress Cake 5 branch (≈1,000 commits), while a CurrencyConverter plugin fails due to a missing Time class.
